Other Abstract

 Soil permeability had great effect on the growth and the water use efficiency of sweet potato. In this
study,responses of photosynthetic characteristics of sweet potato to soil permeability in different soil textures and
soil water conditions were observed through a pot experiment. Results indicated that soil permeability had signifi-
cant effect on the transpiration rate and water use efficiency of sweet potato. When the soil permeability became in-
creased,the transpiration rate became decreased,but the water use efficiency was increased. Also,it seemed that
soil permeability did not affect the photosynthetic rate of sweet potato. In addition,it was found that the effects of
soil permeability on the transpiration rate and water use efficiency were related to soil compositions. Permeability of
sandy soil showed no effect on photosynthetic rate,transpiration rate,and water use efficiency. However,loam soil
decreased the transpiration rate and increased the water use efficiency. The effects of soil permeability on the photo-
synthetic characteristics were also related to the growth period of sweet potato,resulting in various response pat-
terns. These results showed that the impacts of soil texture,water,and growth period must all be taken into consid-
eration when analyzing the responses of crops to soil permeability.
